This is how Physics should be taught!! I was confused between them for a long time...but thank god I found your video.. thank you very much Khan Academy!
So practical, i would love to study entire physics if YOU are my physics teacher, literally ( not joking!) If You will teach me physics, I am ready to pursue physics as my career option🥺❤️
I dont know why students are watching alakh pandey and other unacedemy, vedantu. They dont know there is a genius channel khan academy. And really thanks sir for making a revolution in education
Great video as always. Just one small point. When more current is drawn, the charges don't move any faster, but more charges are pumped per unit time. Current is the flow rate of charge (charge density per time) not its velocity. The travelled distance per unit time per charge (charge velocity) is not affected. More charges require more work (energy) to go through the internal resistor, and the more work is done per unit time, the greater amount of energy is lost as heat.
Mahesh sir and Khan Academy have had an incredible impact on my education and my life. Mahesh sir taught me with clarity and passion, while Khan Academy was my go-to resource for everything. As I move forward, I will carry their inspiration and lessons with me always. I am forever grateful to them. 🌟
Honestly, i saw many videos on RUclips but this video and only this one has given me a lucid understanding of the concept. Heartfelt gratitude to you sir!
I was never explained it so well. Alas! Concepts aren't taught well in some institutions. On the other hand, sir u have done an awesome job. Your a true gem. Understood it crystal clear. Really appreciate.
Really a great video !!! You taught it very well,saw a lot of videos but never understood the topics that clear ...............So, thanks for being here .
Such an underrated video this video give us clear understanding of voltage EMF but sir if please make a video on how is potential difference created inside a cell
I liked it enough to hit the subscribe button first than like button.Support this guy and motivate him to make more of such videos , once again an outstanding applause from me
Excellent explanation... I finally came across the real meaning of these terms. After watching hell lot of videos, I can confidently say that this one was the best✨ Thank you!!!
Woww ! Mind blowing...I just kept on reading and remembering this topic but after watching this video I can understand everything and relate to the definitions and text given in the book...Oh my goodness, thanks a lot !
In parallel circuits the voltage across the batterry and the resistors is the same, but it does still get reduced as we add in more resistors in parallel (because more current = more heat loss = reduced terminal voltage).
10:57 I think that is a wrong statement because drift velocity of electrons is always constant. You should have said more number of electrons are being transferred through unit cross section per unit time and hence more heat energy. Correct me if I am wrong
I think it is incorrect to say that charges move faster or slower through a circuit. Rather it is the amount of current that changes. More current through the battery means that more heat is dissipated by the internal resistance of the battery.
That is happening because more and more energy will be lost to the internal resistance in a real life situation as the current drawn increases when more batteries are connected
Voltage is constant for a given number of resistors, not if you keep adding resistors. Suppose you have 3 resistors (Call them A,B and C) in parallel. The voltage across each resistor, V is constant or each resistor has the same potential difference across its ends. Now you add another resistor D in parallel to the other 3. In this case the voltage will change to some V’. Across each resistor A,B,C and D , the voltage is now V’ ( ie. Voltage is constant across each resistor) So voltage varies if you add more resistors. When they say that voltage in parallel is a constant they mean FOR A GIVEN NUMBER OF RESISTORS, voltage is constant
At 2:20 can any one relate the video with ohms law according to it current is directly proportional to voltage so as per my thinking if more current gets drawn more voltage should be passed
This is how Physics should be taught!!
I was confused between them for a long time...but thank god I found your video..
thank you very much Khan Academy!

Teachers like you give us clear understanding of physics.
I actually feeled what might be happening in the battery through this vedio
And that was amazing 👍👍
My friend, this is totally different, I wish you were my teacher when I was in high school. really awesome. Thanks a lot.
Many videos on this topic but it only this one where i understood. Thank you sir! Best Physics teacher with incredible content 🤩
crazy how well this guy explained not only emf , tv and ir , but also the fundamental nature of how charges and voltage works
Well done mate
This is the best explaination of this topic forever
Love your explanation 😍😍
Really a great video !!! You taught it very well,saw a lot of videos but never understood the topics that clear ...............So, thanks for being here .
It's just not clear, it's crystal clear
Thank you soo much for this extraordinary explanation sir...👏👏👏
Just assuming this channel will now continue with its videos post elon musk huge 5 million dollar donation to khan academy recently 🤗🤗🤗🤗🤗🤗🤗🤗
I was finding a great problem with emf and terminal voltage but now it's crystal clear
Such an underrated video this video give us clear understanding of voltage EMF but sir if please make a video on how is potential difference created inside a cell
This video deserves a lot than others !!! ✌🌟🔥
Thank you sir, I have been confused in this topic from my academic year, now it's crystal clear !!
EPIC EXPLANATION, SIMPLY EPIC. Thanks a lot, Sir!
10:57 you say the terminal voltage drops
I say the mic drops
Respect 💯

Love u r explanations man,and highly appreciating for the efforts you put to make us understand.
Crystal clear!! ⭐ Thank you sir ❤
The charge can be negative too right? Using which he explained EMF?
I am telling you..... This is the best explanation I have seen about this topic in the entire feed
Mahesh sir, I dont have any words to express how much grateful I am to you for these explanation videos.
I like the fact that he gives more importance in your explaining the concept not the derivation.
Khan academy is soo underrated 😫
Sir thank you for this lucid explaination, you are an incredible teacher ,sir we all aspire to be like you
Thanks, you made it so easy to understand.😁👌even a class 2 student can understand it easily
I don't have any word to tell about how much I am admired you becouse of your interseting detail video
This video saved my life...Honestly...I watched many videos but this one.I don't have words
Thank you so much for making me understand this concept 🥰🥰
The explanation is very lucid. I have finally got it and will be able to explain it to my daughter. Thank a zillion.

This is incredible. Wow first time I felt like it's not phy but a story that got into my head right at the moment.
Literally watched 5 videos of this topic and this the only one that made me understand the concept till depth.
u r such a gem🔥

Finally I've watched a perfect explaination on this topic it's so confusing for me but I'm glad now my doubts are almost clear 🙂thanks
Best video I’ve seen so far❤❤❤thank you!🎉
in parallel circuit voltage remains same right so why will the bulb glow less brightly as you told in the beginning?
In parallel circuits the voltage across the batterry and the resistors is the same, but it does still get reduced as we add in more resistors in parallel (because more current = more heat loss = reduced terminal voltage).
@@jax1296 ahh yes thank youu!!
You just killed the concept....love from india❤
Dudee u just cleared topic in 14 min and that to crystal clear❤ thanku
Only video that made me understand this topic❤❤❤
Happy teacher's day sir
This helps a lot thank you I was wondering what was going on when this was taught in class this certainly helps me thank you
This was very helpful🙏❤️❤️
I'm speech less ,you're the one my best tutor in my way thanks for your process and thoughts to do this great job without any bubble reputation
Hope to see more videos of you sir! You helped a lot! ♥️✨
No words for your wisdom 😀
10:57 I think that is a wrong statement because drift velocity of electrons is always constant. You should have said more number of electrons are being transferred through unit cross section per unit time and hence more heat energy.
Correct me if I am wrong
No. of electrons/volume always remain constant
The speed of current can definitely inc/ dec
You can't change the number of electrons
Thank you so much sir 😊😊....after watching this video my concepts are crystal clear🤩🤩
Honestly speaking...it's the best of explanation.
Cleared all my doubts. Thank you!
Thank you so much🎉
I see it clearly now.
I like your video. You take the time to explain slowly. My brain doesn't catch up too quickly.
Crystal clear✨
To the point
Veryy nice✌🏻
very very nice video please don't stop making this type of videos
Amazing video 🎉
I think it is incorrect to say that charges move faster or slower through a circuit. Rather it is the amount of current that changes. More current through the battery means that more heat is dissipated by the internal resistance of the battery.
Can you explain how current increases if velocity of electrones is kept constant?
Very good explanation.😊😊😊😊
May God Bless you
Words can't explain how u have helped me
Beautiful video, Thanks Boss.
Bro this was so educational! I wasn't getting a thing in the chapter of Cells but tysm this rlly helped out a lot!
Thanks my teacher teaches from our course Books 📚 u sir said it more clearly 🎉
Tnq so much for such an easy explanation ✌✌just love it and u made the topic easier for us
Very Nicely Explained ❤❤
When more current is drawn so voltage drop but normally in parallel we know that in parallel combination the voltage is constant right!!!!
That is happening because more and more energy will be lost to the internal resistance in a real life situation as the current drawn increases when more batteries are connected
Yes, I too was having the same doubt 😐🙄
@@aog3367 that is ideal source but practically its impossible
Voltage is constant for a given number of resistors, not if you keep adding resistors.
Suppose you have 3 resistors (Call them A,B and C) in parallel. The voltage across each resistor, V is constant or each resistor has the same potential difference across its ends.
Now you add another resistor D in parallel to the other 3. In this case the voltage will change to some V’. Across each resistor A,B,C and D , the voltage is now V’ ( ie. Voltage is constant across each resistor)

It is just wow dude!
Ifkr
I am very grateful for your detailed explanation 😊
At 2:20 can any one relate the video with ohms law according to it current is directly proportional to voltage so as per my thinking if more current gets drawn more voltage should be passed
current is directly proportional to voltage(Ir- loss as heat/coulomb)
when (Ir- loss as heat/coulomb) increases, terminal voltage decreases
Thanks man this was a great explanation and I just loved the way this concept was explained.
14min 30 sec worth worth worth now I love to study physics ❤

Thank you so much I can say I was suffering with not understanding this topic.❤❤
sir, but voltage remains same, i.e it remains unaffected in parallel circuits right?
Yup ....I was also thinking the same ...can anyone answer?
